A mechanism should always serve a purpose

Going to the ballet a couple of weeks ago I realised that there are a lot of hand gestures. Welcoming people in, showing them around, pointing to this and that, gesturing that he and she are getting married etc. They are beautiful graceful movements. The hands move at the end of the arm movement and finish the movement. The hand movement is an extension of the arm movement. So I wondered if using a simple mechanism we could make the hand do that. Here is is a trial version with a cardboard hand. The next challenge is to make the hand light enough to replciate that movement.
